IMPORTANT SAFETY NOTICES
PREVENTION OF PHYSICAL INJURY
1. Before disassembling or assembling parts of the copier and peripherals,
make sure that the printer power cord is unplugged.
2. The wall outlet should be near the printer and easily accessible.
3. Note that some components of the printer and the paper tray unit are
supplied with electrical voltage even if the main power switch is turned off.
4. If any adjustment or operation check has to be made with exterior covers off
or open while the main switch is turned on, keep hands away from electrified
or mechanically driven components.
5. The inside and the metal parts of the fusing unit become extremely hot while
the printer is operating. Be careful to avoid touching those components with
your bare hands.
HEALTH SAFETY CONDITIONS
Toner, including monocomponent toner, and developer are non-toxic, but if you
get either of them in your eyes by accident, it may cause temporary eye
discomfort. Try to remove with eye drops or flush with water as first aid. If
unsuccessful, get medical attention.
OBSERVANCE OF ELECTRICAL SAFETY STANDARDS
1. The printer and its peripherals must be installed and maintained by a
customer service representative who has completed the training course on
the appropriate models.
2. The NVRAM module (option) installed on the controller has a lithium battery
which can explode if replaced incorrectly. Replace the NVRAM only with an
identical one. The manufacturer recommends replacing the entire NVRAM.
Do not recharge or burn this battery. Used NVRAM must be handled in
accordance with local regulations.
SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL
1. Do not incinerate toner bottles or used toner. Toner dust may ignite
suddenly when exposed to an open flame.
2. Dispose of or recycle as required, used toner, developer, and organic
photoconductors in accordance with local regulations. (These are non-toxic
supplies.)
3. Dispose of or recycle as required, replaced parts in accordance with local
regulations.
LASER SAFETY
The Center for Devices and Radiological Health (CDRH) prohibits the
repair of laser-based optical units in the field. The optical housing unit
can only be repaired in a factory or at a location with the requisite
equipment. The laser subsystem is replaceable in the field by a qualified
Customer Engineer. The laser chassis is not repairable in the field.
Customer engineers are therefore directed to return all chassis and laser
subsystems to the factory or service depot when replacement of the
optical subsystem is required.
WARNING
Use of controls, or adjustment, or performance of procedures other than
those specified in this manual may result in hazardous radiation exposure.
WARNING
WARNING: Turn off the main switch before attempting any of the
procedures in the Laser Unit section. Laser beams can seriously damage
your eyes.
